LOC OMOTlVE-SPRlNGr SPECIFICATION forming part of Letters Patent No. 355,069, dated December 28, 1886.

Application filed March 16, 1886.

Serial No. 195,429. (No model.)

' T all whom, it may concern.-

Be it known that I, JOHN RANDOLPH FISH, of Grand Rapids, in the county of Kent and State of Michigan, have invented a new and Improved Locomotive-Driving Spring Device, of which the following is a full, clear, and exact description.

My present invention relates to the construction of a locomotivedriving spring device, and the invention consists of a modification of theinventionillnstrated, described, and claimed in Letters Patent No. 296,545, granted to me on the 8th day of April, 1884, whereby the general construction illustrated in said patent is rendered available for use in connection with the frame supporting the drivingwheels of a locomotive.

Reference 'is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of a portion of alocomotive-frame provided with my improved form of spring and equalizing attachment. Fig. 2 is a plan View of the same. Fig. 3 illustrates the construction of the saddle sup porting the springs; and Fig. 4 is an end view of the equalizing-bar, representing the same as detached from the other parts.

In the drawings, A represents the frame of the locomotive, which frame is provided with a vertical post, B, that passes through a central aperture, a, formed in the equalizing-bar C, the parts being held together by a key, 22, or by any other convenient'means for forming a pivotal connection bet-ween the post and the equalizing-bar.

The frame A is formed with jaws 0 0, in which the driving boxes on are mounted.- Spring-saddles T, formed, as best shown in Fig. 3, with lugs t t, which straddle the upper bar of the frame A, are'placed in the position best shown in Fig. 1, so as to rest upon the top of the box in. Upon these saddles T there are mounted spring-seats D, provided with downwardly-projecting cylindrical bearing-blocks c, which rest in grooves d, formed in the upper face of the saddles. As many springs E' as may be required to properly support the weight of the locomotiveboiier are mounted upon the seats D, and the ends of the equalizing-bar 0 project over these springs, each end .of the bar 0 being provided with as many downwardly-projecting posts 0 as there are springs carried by the seats D.

The advantage arising from the construction above described is that all spring-hangers are dispensed with, and altogether the improvement described results in a better as well as a cheaper and more durable arrangement. deemed desirable, the springs E could be placed under the box m,- but in this case the spring-seats would be suspended from the box, and the equalizing-bar would be pivotally connected with the lower horizontal bar, instead of the upper horizontal bar, of the frame.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the frame, the boxes, and the vertical bearing intermediate thereof, of the equalizing-bar mounted onthe vertical bearing and extending at its opposite ends to a point in vertical alignment with the said boxes, bearings on the boxes, and springs resting at one end on the boxes and at their opposite ends on the ends of the equalizing bar,substantially as set forth.

2. In a locomotive, the combination, with a frame provided with a verticalpost, of an equalizing-bar provided with a central slot through whichsaid post is passed, a key, I),

springs E, seats D, saddles T, and boxes m, all substantially as described.

3. In a locomotive-driving spring device, the combination, with a frame provided with a vertical post, of an equalizing-bar centrally slotted toreceive said post; and extending over two sets of springs E, that are mounted in seats D, that are free to rock on saddles T,
